Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention, it should be noted that not
Under the premise of conflicting, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
Embodiment 1
As shown in Figure 1, being the anti-blocking ink jet numbering machine of one embodiment of the present invention.The anti-blocking ink jet numbering machine includes central controller
P1, ink jet numbering machine ontology P2 and nozzle protecting device P3, central controller P1, ink jet numbering machine ontology P2 and nozzle protecting device P3 pass through
Built-in circuit connects, and is attached and controls by electric signal between above equipment.In other embodiments, central controller
P1, ink jet numbering machine ontology P2 and nozzle protecting device P3 can also be connected by such as bluetooth, WIFI either RFID, be had identical
Connection and control effect.
When carrying out ink-jet using the ink jet numbering machine ontology P2, firstly, central controller P1 sends open signal to nozzle guard
Device P3, nozzle protecting device P3 receive the nozzle of opening ink jet numbering machine ontology P2 after open signal, at this point, ink jet numbering machine ontology P2
Nozzle is exposed in air.It is connect again by central controller P1 transmission ink jet signal to ink jet numbering machine ontology P2, ink jet numbering machine ontology P2
Receive ink jet signal after start ink jet process, spray corresponding code and be attached to corresponding coding carrier (such as can be carton or
Person's plastic packing box) on, it dries, at code.The nozzle that ink jet numbering machine ontology P2 is automatically turned on by setting nozzle protecting device P3, saves
Shi Shengli is precisely controlled the ink jet numbering machine and opens nozzle protecting device P3 in a suitable case, guarantees the normal fortune of the ink jet numbering machine
Row.
When not needing to carry out coding using the ink jet numbering machine, that is, when ink jet numbering machine ontology P2 being needed to stop ink-jet, center control
Device P1, which is sent, to be stopped stopping ink-jet after ink jet signal receives stopping ink jet signal to ink jet numbering machine ontology P2, ink jet numbering machine ontology P2.So
Afterwards, central controller P1 sends shutdown signal to nozzle protecting device P3, and nozzle protecting device P3 is blocked after receiving shutdown signal
The nozzle of ink jet numbering machine ontology P2.As a result, when not needing to carry out coding using the ink jet numbering machine, is automatically controlled and sprayed by the ink jet numbering machine
Mouth protective device P3 blocks the nozzle of ink jet numbering machine ontology P2, and the nozzle of ink jet numbering machine ontology P2 is prevented to be exposed in air for a long time,
Because the ink at nozzle volatilizees, solidification is so that block the nozzle of ink jet numbering machine ontology P2, it is ensured that the ink jet numbering machine long-term use process
Middle normal operation ensure that next record spray printing meets the requirement of normal use.
As preferred embodiment, which further includes photoelectric sensor P4, and photoelectric sensor P4 is for detecting spray
Code carrier.In a particular embodiment, when coding carrier is placed in correct coding position, photoelectric sensor P4 is detected
Coding carrier simultaneously sends first detection signal to central controller P1, after central controller P1 receives first detection signal at this time
Open signal is generated, central controller P1 sends open signal to nozzle protecting device P3, and nozzle protecting device P3 reception is opened
The nozzle of ink jet numbering machine ontology P2 is opened after signal, at this point, the nozzle of ink jet numbering machine ontology P2 is exposed among air, such as above-mentioned, spray
Ink recorder ontology P2 starts ink-jet.When coding position vacancy (for example, the incorrect placement of coding carrier either coding carrier leakage
Inspection), photoelectric sensor P4 is equally able to detect coding position, and photoelectric sensor P4 sends the second detection signal to center and controls at this time
Device P1 processed, central controller P1 receive the second detection signal and generate shutdown signal, and central controller P1 sends shutdown signal extremely
Nozzle protecting device P3, nozzle protecting device P3 pass through movement after receiving shutdown signal to block the nozzle of ink jet numbering machine ontology P2.
As a result, by setting photoelectric sensor P4 with real-time detection coding position whether correct placement coding carrier, be based on photoelectric sensing
The detection signal of device P4 controls the overall operation process of ink jet numbering machine, has coding efficiently, precisely, operating process the degree of automation
High, time saving and energy saving effect.
As preferred embodiment, which can also include warning device, when coding position vacancy, photoelectric transfer
Sensor P4 is equally able to detect coding position, the second detection signal of photoelectric sensor P4 transmission at this time to central controller P1, in
After entreating controller P1 to receive the second detection signal, while alarm signal is generated, central controller P1 sends alarm signal and extremely alarms
Device (not shown), starting alarm.Operator can be reminded in time in the case where there are coding abnormal conditions by the way that warning device is arranged,
Abnormal coding carrier is replenished in time or converts the riding position of coding carrier, guarantees the normal coding of coding carrier, prevents coding
Abnormal conditions occur.
As preferred embodiment, when coding position vacancy, photoelectric sensor P4 detects coding position and sends the
Two detection signals are to central controller P1, at this point, the central controller P1 timing coding position vacancy time.If coding position is empty
Lacking the time is more than specific duration, such as can be 30s~5min, show it is next to coding carrier occur it is abnormal (such as may
It is to omit, improper put), at this point, photoelectric sensor P4 sends shutdown signal to nozzle protecting device P3.It is controlled by center
The device P1 timing coding processed position vacancy time, it can effectively assess the interval time transported between coding carrier.Coding position is empty
When lacking the time less than coding carrier transport time-consuming, show that coding carrier is still in during normal transport, central controller P1
It is in the open state to control nozzle protecting device P3.When the coding position vacancy time is greater than coding carrier transport time-consuming, show to spray
Code carrier is likely to occur abnormal conditions, and central controller P1 control nozzle protecting device P3 blocks nozzle, stops ink-jet, effectively anti-
Stop nozzle to be exposed among air to cause to block for a long time, can also prevent the feelings of the improper closing of nozzle protecting device P3
Condition.In a specific embodiment, coding position allows the duration of vacancy can be adjusted according to the actual situation, such as simultaneous simultaneously
Care for the time and coding carrier transport time of ink jam nozzle, it is ensured that in the standard duration, nozzle is unlikely to block, coding
Carrier also can normal transport to coding position.
